With a duplex which are super common in Milwaukee you are in that in-between space where most owners try to make the tenants do it, but that can be tricky.

In Franklinton there are plenty of large projects going on that will bring massive growth to the west side of Columbus, such as the Peninsula Development, which is a multiphase project that will erect a 24 story apartment complex featuring a grocery store, a multi use office space building, and a new hotel featuring a two-story venue.

My wife is an artist /interior decorator too and makes beautiful spaces on a budget, so would kill it with MTR, I think. 

as mentioned above i would find a househack property in need to cosmetic upgrades that has below market rents. make the necessary upgrades (ie. appliances, flooring, paint, laundry, fixtures) allowing yourself to bring the property up to market rent standards and increasing the rent.I'm not too familiar with the market/properties in MI but in central MA we have a lot of triple deckers that are 100+ years old.

It DOES NOT require a full gut rehab (rehab could consist of new kitchen, new bath(s), windows, flooring, paint, etc.

Keeping it as one big space may set it apart from standard storage units, but you could also test demand with dividers for varied price points.

A two-story, eight-unit apartment building with four units on each floor, each offering two bedrooms and one bath.

We also paid them 2,600 for the cost of the flooring, which they have mostly completed. 

On paper, the numbers work, it currently has renters in place, although month to month and one unit is actively trying to move somewhere else because they need more space. 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.
